LexiSponge: Vocabulary Builder

LexiSponge is a vocabulary-first language learning app built around a simple idea: every new word you meet should have a place to go. Start with an empty vocabulary page and build your own language "second brain". Add words manually, or capture them from the things you already read, watch, hear, and photograph. LexiSponge helps turn text, images, camera captures, and recordings into vocabulary you can organize, review, and remember. Capture new words: - Add words manually whenever you notice them - Extract vocabulary from text - Capture words from images or your camera - Add words from audio and recordings - Import supported flashcard decks - Add common words to build a foundation faster Organize your language brain: - Tag words by topic, book, video, class, trip, or goal - Mark words as Known, Learning, or Ignored - Keep useful words visible and hide noise - Build a personal vocabulary database that grows with you - See the sentences words appear in Practice with smart flashcards: Turn vocabulary into flashcards and review them on iPhone or Apple Watch. LexiSponge uses FSRS v6, a modern spaced-repetition algorithm designed to schedule reviews when they are most useful, so you can spend more time learning and less time deciding what to study next. Smart Subtitles: LexiSponge’s experimental Smart Subtitles are designed for real listening practice. Instead of translating every sentence, you can focus only on selected words: show translations for words marked as Learning or Unknown, and keep the rest out of the way. This helps you listen to the original language, follow what is being said, and notice the vocabulary you are actively learning. For serious learners: LexiSponge is useful whether you are reading articles, watching videos, listening to conversations, studying with textbooks, preparing for travel, or building a long-term vocabulary system. Experimental tools include: - Smart Subtitles for focused listening - Apple Watch flashcard practice - Import from supported Anki flashcard formats - Export for supported Yomitan dictionary workflows - Common-word vocabulary setup LexiSponge is not just a dictionary, translator, or flashcard app. It is a place to collect the words you meet, decide what matters, and keep learning them across your daily life.
